upscale vosr2 workflow
VOSR 2.0 image upscaler. Send a small, blurry or low-quality picture and get back a sharp, detailed one, 4x bigger by default. It is a one-step AI restorer (1.4B parameters), so it is fast, needs no prompt, and rebuilds fine detail such as textures, faces and small text instead of just stretching pixels. Reply to an image, or attach one. Nothing else is required. Controls: slot1 = upscale factor (default 4; 2-4 gives the most reliable results) /seed = changes the invented fine detail slot2 = colour match to the original: wavelet (default), adain or none slot3 = tile size in pixels (default 512; the model was trained at 512 so keep it for big outputs) slot4 = tile overlap (default 64) slot5 = VAE tile size (default 1024; stops out-of-memory on large outputs) slot6 = VAE tile overlap (default 128) Good to know: the added detail is generated to look right, not guaranteed to be what the original scene really contained, so do not use it as evidence. Keep the input small (under about 1000 px on the long side) so the result stays within the time limit.

This is how it works behind the scenes. This is already configured for you. The parameters in the table above plug into these slots, allowing you to change how it works and which models get loaded. You don't have to understand or modify this - it just works, already set up.
